Technical developments are occurring at a rapid pace due to the increasing demand for new materials and more sustainable production processes on the way to a cleaner world. The challenge of meeting the demand for new technologies is increasing and requires us to think and act more and more creatively.

No matter how much work is being done on processes that no longer burden the environment and are climate-neutral, we are still dealing with existing installations and production techniques. It is impossible to reasonably expect that a turnaround can be achieved within a few years. However, it is possible to adapt existing processes in such a way that the burden on people and the environment is kept to a minimum.

Ravebo has been active for decades in developing and building custom-made industrial scrubbers for gas cleaning. The area of application is particularly versatile: from steel to foodstuffs, from chemicals to building materials, from reducing odor nuisance to removing particulate matter, and for flue gas cleaning.

In recent years, due to the obligation towards cleaner production processes, increased recycling of materials, and reuse of products, the emphasis on the development of scrubbers has evolved significantly.

Previously, a scrubber was considered an end-of-pipe system that required a certain reduction of contaminants. Nowadays, the call for sustainability and the tightened emission limit values not only have a significant influence on the configuration, but the scrubbers must be realized as a completely turn-key project. This means, for example, that control systems must be included, emissions must be monitored in situ with specific, high-end gas analyzers and the recuperation of the washing liquids must be realized.

At the same time, new applications for scrubbers have emerged, such as cleaning syngas from pyrolysis processes, odor reduction at biomass fermentation, gas cleaning when manufacturing biofuels and gas purification in metal recycling.

We use On Topic to highlight the latest news about groundbreaking processes and sophisticated applications. We trust that we can make a sustainable contribution to a cleaner environment, and we strive for a more livable world.
